Presentation

minimal degreeμ(G) = 24
transitive degreeμt(G) = 64

A minimal faithful permutation representation — 3 generators on 24 points:

(2,6)(3,4)(7,8)(9,10)(11,19,22,23)(12,16)(13,17)(14,18)(15,21,24,20);(1,2,4,8,5,7,3,6)(9,11)(10,15,18,24)(12,20)(13,21)(14,22)(16,23,17,19);(2,7)(6,8)(9,12,14,13)(10,16,18,17)(11,20,22,21)(15,23,24,19)
